CHARLES NAGELE, 0F CONSI-IOHOCKEN, PENNSYLVANIA, ASSIGNOR T0 LEE. TIRE RUBBER 00., OF CONSHOHOCKEN, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA.

To all who'mitmay concern: Be it known that I, CHARLES NAGELE, of Conshohocken, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Automobile-Horns,whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates more particularly to an automobile horn which is adaptedto be attached to the exhaust pipe of an automobile, whereby the horn may be operated by the exhaust gases.

An object of the invention is to provide a horn of the above character, which is so constructed that the exhaust gases trapped in the end of the exhaust pipe or body of the horn, are forced therefrom through an open ing in the side wall of said body portion across the pipes.

A further object of the invention is to provide an automobile horn of the above character which shall be simple in construction, and of few parts.

In the drawings, Figure I, is a top plan view of a horn embodying the improvements. Fig. II, is a side view of the same. Fig. III, is a vertical sectional view between the pipes and longitudinal horn.

The horn consists of a body portion 1, which is adapted to be attached to the end of the exhaust pipe '2, of an automobile. This body portion is formed with an opening 3, at its outer end, the wall of which is slightly inclined to the longitudinal axis of the exhaust pipe. Said body portion is provided with an inwardly and downwardly projecting wall 4, which has a seating lug 5, against which a valve 6, rests when the end 3, of the pipe is open. pivotally supported on a rod 7 which extends transversely across the end of the body portion of the horn, and said rod is located in a horizontal plane, passing substantially centrally through the exhaust pipe. The valve 6, extends beyond the rod 7 so as to form a closing portion 8, for the open end 3, in the horn. The body portion is also provided with an upwardly projecting part 9,

which as herein shown is closed by a flat plate 10. This flat plate is provided with a transverse slot or auxiliary opening 11, which lies in a plane cutting the axis of the exhaust pipe at right angles. The sound- Specification bf Letters Patent.

. horn and the plate lOformasubstantially closed chamber "15.

IVhen the valve is in the position shown in Fig. III, the exhaust gases pass underneath the valve out through the open end thereof; IVhen, however, the valve is turned to the position indicated in dotted lines in said figure, then the gases are trapped in the chamber 15, and are forced outwardly through the slot 11, in a direction substantially at right angles to the travel of the gas through the exhaust pipe and across the open mouth of each sounding horn 12, and 13. By this construction it will be noted that when the valve is moved a slight distance from that shown in Fig. III, the gases passing around the inner end of the valve will be trapped in said chamber, and as soon as the valve is in full closed position, there is a considerable volume of gastrapped and ready to be forced out through the slot 11. This trapping of the gases so to speak, and the forcing of the volume thereof out through the slot 11, causes the horn to be sounded, though the volume of gas is comparatively slight.

The valve is held in open position by a spring 16, which is attached at one end to a lug 17, secured centrally of the portion 8, of the valve 6, the other end of the spring being secured to a suitable lug on the bracket plate 14. The valve is closed by an arm or plate 18. This plate as shown in Fig. II is in the form of a segment, having a plurality of apertures 19, therein into which the operating rod may be attached. The plate which projects downwardly from the valve engages the rod 7 and forms one supporting bearing for the valve, while the other supporting bearing is formed by a downwardly projecting ear indicated at 20, in Fig. III.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claim.

Having thus described my invention, I claim:

An automobile horn including in combination, a tubular body portion adapted to be attached to the exhaust pipe of an automobile, the outer end of said body portion being extended laterally, a plate for closing said laterally extended portion, said plate having an opening therethrough, two sounding pipes of difierent lengths supported by the body portion in operative relation to said opening, said body portion having an inwardly projecting partition located at the inner side of said laterally projecting portion and forming a compartment in said laterally projecting portion, a valve having a part adapted to close the open end ofthe tubular body portion and a part adapted to rest on the wall to close the compartment 26 when said end is open, a bracket plate secured to the open end of the body portion and forming the outer wall of said compartment, a spring secured at Oneend of the bracket plate and at its other end to said valve for normally holding the valve so that said compartment is closed, a segment arm' attached to said valve and having a plu rality of apertures therein adapted to re- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents; Washington, D. 0.
